You need to edit /etc/ttys and change status to "off" for the
appropriate tty, then "kill -1 1" to tell init to reread /etc/ttys. If
you just kill the getty init will restart it.
However, there is still a bug. The system shouldn't crash. It
should either error out when the tty is in use, or forcibly detach all
processes from the tty.
